Abstract

A two-cycle engine having a cylinder (ll), an exhaust port (l5a) through the wall of the cylinder and an exhaust passage (l5) extending from the exhaust port with an exhaust timing control device located in the exhaust passage. The device includes a valve body l9 which, in a first embodiment, is pivotally mounted in the exhaust passage and extends to the exhaust port. In a second embodiment, the valve body (30) is fixed at one end and operates as a flexible resilient member to achieve variation in timing control. Each valve body is biased against a cam mechanism (26) which may be rotated to actuate the valve body for controlling exhaust timing. The cam also provides a sealing mechanism between the valve body and the upper surface of the exhaust passage.
